vIMPBOVED GAS APPARATUSFOR DOMESTIC USE.

Specification forming part of Letters Patent No. 39,159, dated .1 uly V'7, 1863.

do hereby declare that the following is afull, clear,and exact description of the same, reference being had tothe accompanying drawings, forming 'a part of this' specification, in which- Figure 1 represents a longitudinal vertical section of our invention. Fi g. '2 is a transverse vertical section of the' same.

Similar letters of reference in both views 'indicate corresponding parts. The object of this invention is to produce a gas apparatus capable of supplyingadwellinghouse with gas, and so simple'and cheap n'its construction and operation that itcan readily be'put up and operated in every/house.

'The invention consists in the employmentor use of a zigzag or winding. concave' or perfo-V rated tube rising gradually through'the -puritier 'in such a mannerthat .the gas'is com-- pelled to travel a long distance through the small quantity.

water, and is well washed in a comparatively i l ll The invention consists, finally, in the arrangement of a limefchamber in the movable lidA of the purifier havinga screen 'or 'perfo- .rated bottom to support-the lime and admit the gas, said lid belng connected' withtheconducting-pipes by a liexible tube, so that it can be removed without breaking theconnections.

To enable othersskilled inthe art to make' and use our invention, we will proceedto des scribe it.

A represents the pipe leading from the re-` tort to the tar-receiver B. Said pipe is so 'ar--V ranged that the upper portion of it on that part emanating from the retort can be 'readily removed V ,v'v'henever thev gas apparatus is not in operation; It extends down near to the bottom of the receiver B, which ispartiallyilled with water'and provided with a suitable gate or faucet todraWolT- the t'ar which collects at its bottom. At .thesame time the aqueous. vapors contained in the gas are condensed in the receiver and the gas'partially puried escapes through the pipe C to the'pu'rilier D. The pipe C exten-ds from 'the top of the tarreceiver to the bottom of the purifier, as clearly shown -in Fig.' 1 of the drawings', The purilier -is tobe nearly filled with water and it isprovided vvv ith a series of semicircular concaves, E, inclined opposite directions and provided withopen` ings a, each at or nearftoits'highest end, so that a rising lzigzag" passage `isformedrand the gaswhich enters througli'fthe pipe QQu'nder the lower end ofthe'bottorn concave, will.' pass along under this concave tothe-opening 'at its highest end, through this openingto the lowest end of the second concave, and: so on, until it reaches. the opening in the highest end of the topconcave. In taking this zigzag course the gas is'co'ntinually'in contact with the wa'ter in `the purifier, and :1t-comparatively `small quantity of' water. is `sufficient Vto wash the gas.

It is obvious that instead of a zigzagl passageaspiral or polygonal rising passage might be formed by the concaves E, and'instead of using .semicircnlar concaves, pipes might bel used, perforated at t-he'bottomto admit lthe water. from' the purifier. A- vF is the lid of the puriier,wh'ichi s provided with a screen or perforated' bottoni', b, 'covered with limev or other suitable material, capable of absorbing the impurities still remaining inV the gas. After having passed' through the lime chamber, the gas rises through the pipe cinto the gas-holder H., where it is retained for use. This gasholder is made of some ilexible material, and it is soarranged that it can be loaded with `sufficient weight to drive out the gas withtheldesired pressure.- The tube I, which conducts the gasfrom the purifier to ythe burners, is made' of some iiexiblematrial, thus allowingof removing the lid F without breaking the connections, whenever it should be' desirable to get to the interior of said'puriier'for the-purpose of cleaning the gas-passage or of recharging it withcle'a water.

This apparatus' is so very simple in its construction that it can readily be put it operation by inexperienced persons, "and by the L'profits derived from the tar collected in the receiver B the cost of the gas vis nearly coveredl v Having thus fully described our iuveution, the movable iid F of the puriler, in com-binawhat We claim as new; and desire to-secure by tion with the flexible .tube I, constructed and Lett-ers Patent, is-
